LED Board

Referring now to FIGS. 12 and 13, LED board 1102 is shown in greater detail, according to some embodiments. FIG. 12 shows LEDs 1004 disposed along path 1206, according to some embodiments. Path 1206 is generally rectangular, according to some embodiments. In some embodiments, path 1206 is generally elliptical, generally square, etc., or any other geometric shape. In some embodiments, LEDs 1004 are spaced non-evenly along path 1206. For example, as shown in FIG. 12, LED 1004 a is disposed a distance 1202 from adjacent LED 1004 b along path 1206, while LED 1004 g is disposed a distance 1208 from adjacent LED 1004 f along path 1206, according to some embodiments. In some embodiments, LEDs 1004 are placed along path 1206 based on a desired function of display device 100. In some embodiments, LEDs 1004 are light emitting diodes. In some embodiments, LEDs 1004 are multi-color LEDs (e.g., red-green-blue (RGB) LEDs). In some embodiments, LEDs 1004 are single color LEDs (e.g., white LEDs). In some embodiments, LEDs 1004 are dimmable LEDs (e.g., brightness can be adjusted, intensity of emitted light can be adjusted, etc.). In some embodiments, LEDs 1004 receive signals through LED board 1102 to cause LEDs 1004 to adjust a brightness of one or more of LEDs 1004. In some embodiments, LEDs 1004 receive signals through LED board 1102 to cause LEDs 1004 to switch from an on-state to an off-state. In some embodiments, LEDs 1004 receive signals through LED board 1102 to adjust a color of one or more of LEDs 1004. Any of the brightness, on/off state, color, etc., of any of LEDs 1004 is adjusted according to one or more predetermined patterns, according to some embodiments. For example, in some embodiments, certain LEDs 1004 (e.g., LEDs 1004 a-c) are actuated between an on-state and an off-state for a predetermined amount of time (e.g., on for 5 seconds, off for 4 seconds, etc.) while other LEDs 1004 (e.g., LEDs 1004 d-i) are not actuated between an on-state and an off-state. Any of the dimming, color, etc., of o any of LEDs 1004 is configured to operate according to a similar pattern, or a combination of patterns thereof.

As shown in FIG. 12, LED board 1102 includes nine LEDs 1004, according to some embodiments. In some embodiments, LED board 1102 includes more or less than nine LEDs 1004.

FIG. 13 shows LEDs 1004 equally spaced along path 1206, according to some embodiments. For example, LED 1004 a is shown spaced a distance 1210 along path 1206 from LED 1004 b, according to some embodiments. In some embodiments, each of LEDs 1004 are spaced distance 1210 along path 1206 relative to a neighboring LED 1004. For example, LEDs 1004 a-b are spaced distance 1210 apart along path 1206, and LEDs 1004 b-c are also spaced distance 1210 apart along path 1206, according to some embodiments. In some embodiments, one or more of LEDs 1004 are offset relative to path 1206. For example, LED 1004 a is offset a predetermined amount from path 1026, according to some embodiments. In some embodiments, each of LEDs 1004 are proximate a portion of halo 112.

Halo

Referring now to FIGS. 14-19, halo 112 is shown in greater detail, according to some embodiments. In some embodiments, halo 112 is configured to receive light emitted by any of LEDs 1004 and direct, diffuse, scatter, etc., the emitted light along at least one of sides 108. In some embodiments, halo 112 is configured to produce a glow along at least one of sides 108. Since LEDs 1004 can be configured to operate in a patterned manner (e.g., on-state, off-state, brightness, color, etc.), halo 112 may diffuse, direct, scatter, etc., the emitted light along at least one of sides 108 according to a currently used pattern, according to some embodiments. In some embodiments, halo 112 facilitates a glow along sides 108 of display device 100. In some embodiments, halo 112 facilitates indicating a message to a user (e.g., a particular pattern represents and/or corresponds to a particular event). In some embodiments, halo 112 facilitates a wider off-axis viewing angle of the message. For example, in some embodiments, display device 100 is a thermostat. In some embodiments, LEDs 1004 may transition between a blue color and a red color which corresponds to the indoor air temperature of the conditioned space. In some embodiments, the blue color indicates a low temperature, and the red color indicates a high temperature. In some embodiments, a wavelength (λ) of light emitted by LEDs 1004 and directed by halo 112 is dependent on the temperature. In some embodiments, LEDs 1004 emit light at any wavelength (λ) within the visible spectrum of light. Advantageously, this facilitates notifying a user or an occupant of the conditioned space without the user/occupant necessarily being able to observe user interface 106, according to some embodiments. For example, if a user is not in front of display device 100 such that the user can observe user interface 106 directly, the user may still be notified of a changing temperature (or any other variable) of the conditioned space by observing the light emitted from display device 100 by halo 112.

In some embodiments, halo 112 is or includes translucent and/or transparent material. In some embodiments, halo 112 is configured to allow light to pass through. In some embodiments, one or more exterior surfaces of halo 112 are coated with a material which does not allow light to pass through. For example, in some embodiments, all exterior surfaces of halo 112 are coated with a material (e.g., a coating, a paint, etc.)

Referring to FIG. 14, in some embodiments, at least a portion of halo 112 is positioned between front portion 102 and rear portion 104. In some embodiments, at least a portion of halo 112 is positioned adjacent front portion 102 at a first side and adjacent rear portion 104 at an opposite site. In some embodiments, at least a portion of halo 112 is adjacent bezel 218.

Referring still to FIG. 14, an outer edge of halo 112 is shown angled relative to a horizontal axis 1402, according to some embodiments. In some embodiments, the outer edge of halo 112 is arcuate, curved, etc. In some embodiments, halo 112 extends along an entire perimeter of display device 100. In some embodiments, the angled/curved profile of halo 112 facilitates a directing of light. For example, in FIG. 14, an outer edge of halo 112 is angled such that emitted light 1404 is generally directed towards a front of display device 100.

Referring now to FIGS. 15 and 16, halo 112 is shown in greater detail, according to some embodiments. FIG. 15 shows a front view of halo 112, according to some embodiments. FIG. 16 shows a perspective view of halo 112, according to some embodiments. Halo 112 is shown to include light directing elements, shown as wave guides 1504, according to some embodiments. In some embodiments, wave guides 1504 are configured to at least one of direct, diffuse, guide, etc., light emitted by one or more of LEDs 1104. In some embodiments, wave guides 1504 are configured to at least one of direct, diffuse, guide, etc., light emitted by a corresponding LED 1104. For example, wave guide 1504 is configured to at least one of direct, guide, diffuse, etc., light emitted by LED 1104 a, according to some embodiments. In some embodiments, each of wave guides 1504 include a corresponding LED 1104.

In some embodiments, wave guides 1504 protrude from rim 1502 along a curved path. In some embodiments, a width of sweep portion 1508 of wave guides 1504 varies (e.g., decreases) along the curved path. In some embodiments, wave guides 1504 include a receiving post (e.g., a square receiving post, a rectangular receiving post, a square receiving post, etc.) which protrudes from an end point of sweep portion 1508. In some embodiments, any or all of rim 1502, sweep portions 1508 and receiving posts 1506 are integrally formed.

In some embodiments, wave guides 1504 are generally S-shaped and have a first end and a second end. In some embodiments, the second end is configured to receive light emitted by light emitting devices (e.g., LEDs 1004, LEDs 2026, etc).

In some embodiments, rim 1502 is coated with the opaque material. In some embodiments, first surface 1706, second surface 1708 and interior surface 1728 are coated with the opaque material. In some embodiments, if sweep portion 1508 protrudes from interior surface 1728, at least part of an area of interior surface 1728 which sweep portion 1508 protrudes from is configured to allow light to pass through. In some embodiments, exterior surface 1710 is configured to facilitate egress of light from wave guide 1504. In some embodiments, exterior surface 1710 is configured to diffuse light which passes through wave guide 1504 along at least part of exterior surface 1710.

In some embodiments, sweep portion 1508 includes one or more exterior surfaces which are coated (e.g., cladded) with an opaque material configured to restrict the exit of light from wave guide 1504. In some embodiments, sweep portion 1508 includes first surface 1702 and second surface 1704. In some embodiments, first surface 1702 and second surface 1704 are opposite each other and are each offset an equal distance from path 1722 in opposite directions. In some embodiments, first surface 1702 and second surface 1704 substantially follow path 1722 at an offset distance. In some embodiments, first surface 1702 and second surface 1704 are coated (e.g., cladded) with the opaque material.

In some embodiments, an axis 1732 extends tangent to a starting point 1738 of path 1722. In some embodiments, an axis 1734 extends tangent to an end point of path 1722. In some embodiments, axis 1734 is a central axis of receiving post 1506. In some embodiments, axis 1734 extends tangent to the end point of path 1722 and is the central axis of receiving post 1506. In some embodiments, axis 1732 and axis 1734 are substantially parallel to each other. In some embodiments, axis 1732 and axis 1734 are substantially parallel to each other and are offset a distance 1736 from each other. In some embodiments, distance 1736 is a distance which is perpendicular to both axis 1732 and axis 1734. In some embodiments, distance 1726 is parallel to the Z-axis of coordinate system 1700. In some embodiments, axis 1732 extends tangentially outwards from starting point 1738 of path 1722 and starting point 1738 of path 1722 is disposed at a center point of initial width 1740 of sweep portion 1508. In some embodiments, axis 1732 and axis 1734 are offset relative to each other along the X-axis of coordinate system 1700 (e.g., laterally). For example, as shown in FIG. 16,

In some embodiments, sweep portion 1508 has a width 1714. Width 1714 varies (e.g., decreases) along path 1722, according to some embodiments. In some embodiments, width 1714 decreases along path 1722 until it is substantially equal to thickness 1730 of receiving post 1506. In some embodiments, width 1714 decreases non-linearly. In some embodiments, sweep portion 1508 has initial width 1740 proximate the interface (e.g., connection) between rim 1502 and sweep portion 1508. In some embodiments, width 1714 decreases linearly. In some embodiments, width 1714 decreases (e.g., either linearly or non-linearly) along part of path 1722 and increases (e.g., either linearly or non-linearly) along another part of path 1722.

In some embodiments, receiving post 1506 protrudes from an end of sweep portion 1508. In some embodiments, receiving post 1506 protrudes tangentially outwards from an endpoint of path 1722. In some embodiments, receiving post 1506 extends in a direction substantially parallel to the Y-axis. In some embodiments, receiving post 1506 includes a receiving surface 1720, configured to facilitate entry of light emitted by one of LEDs 1004. In some embodiments, all other surfaces of receiving post 1506 are coated (e.g., cladded) with the opaque material to prevent light from exiting through the other surfaces.

In some embodiments, sweep portion 1508 has a constant thickness 1712 along an entire length of path 1722. In some embodiments, sweep portion 1508 has a variable thickness 1712 with respect to path 1722. For example, in some embodiments thickness 1712 increases, decreases, or a combination of both, along path 1722. In some embodiments, thickness 1712 is substantially equal to thickness 1730 of receiving post 1506. In some embodiments, thickness 1712 changes (e.g., increases, decreases, or a combination of both) along path 1722 and is substantially equal to thickness 1730 of receiving post 1506 at an end of path 1722 which receiving post 1506 protrudes from.

In some embodiments, receiving post 1506 has a height 1716. In some embodiments, receiving post 1506 protrudes from the end of sweep portion 1508 such that surface 1720 of receiving post is adjacent LED 1004.

Referring now to FIG. 19, a side view of LED board 1002 and halo 112 is shown, according to some embodiments. In some embodiments, light emitted by LED 1004 is received by wave guide 1504 (e.g., through receiving post 1506), travels through sweep portion 1508, and exits halo 112 through exterior surface 1710 of rim 1502. In some embodiments, light emitted by LED 1004 follows path 1902, generally. In some embodiments, path 1902 is path 1722. In some embodiments, if exterior surfaces of wave guide 1504 are coated (e.g., cladded) with an opaque material, light emitted by LED 1004 travels through wave guide 1504 and reflects off the opaque material. In some embodiments, halo 112 facilitates a glow of emitted light along exterior surface 1710 of halo 112. In some embodiments, halo 112 diffuses light along sides 108 of display device 100. In some embodiments, halo 112 is manufactured from or includes (e.g., at exterior surface 1710) a light diffusing material. In some embodiments, halo 112 is translucent. In some embodiments, halo 112 is transparent. In some embodiments, halo 112 acts as a lens and focuses light emitted by LED 1004 along sides 108. In some embodiments, light emitted by LED 1004 which enters wave guide 1504 is substantially bounded by exterior surfaces of wave guide 1504 and only enters wave guide 1504 through receiving post 1506 and only exits wave guide 1504 at rim 1502.

Halo 112 facilitates a wider off-axis viewing angle of light emitted by LED 1004, according to some embodiments. In some embodiments, halo 112 facilitates notifying a user regarding information received by or determined by display device 100. In some embodiments, halo 112 enables the notification to be visible by an observer generally facing any of sides 108.

Referring still to FIG. 20, controller 2000 is shown receiving information from at least one of sensor/equipment 2036 and controller 2034, according to some embodiments. In some embodiments, controller 2000 receives information from sensor/equipment 2036 and determines an operation of LEDs 2026 corresponding to the information received. In some embodiments, LEDs 2026 are LEDs 1004. In some embodiments, LEDs 2026 are LED board 1002. In some embodiments, controller 2000 is configured to determine an event (e.g., temperature exceeding a threshold value, emergency event, etc.) and is configured to adjust an operation of LEDs 2026 for the event. In some embodiments, controller 2000 receives information regarding an event from controller 2034 and adjusts an operation of at least one of user interface 2032 and LEDs 2026 for the event. In some embodiments, sensor/equipment 2036 is any of a temperature sensor, an air quality detector, building equipment, etc., or any other sensor or equipment. In some embodiments, sensor/equipment 2036 is more than one sensor and/or more than one equipment. For example, controller 2000 receives information from multiple temperature sensors, according to some embodiments.

Controller 2000 is shown receiving information from sensor/equipment 2036 through input interface 2024. In some embodiments, sensor/equipment module 2010 receives the information from sensor/equipment 2036. In some embodiments, sensor/equipment module 2010 receives the information from sensor/equipment 2036 and determines an event based on the received information. For example, in some embodiments, sensor/equipment module 2010 periodically receives temperature information from a temperature sensor and determines if the received temperature exceeds a predetermined threshold value. In another example, sensor/equipment 2036 receives information from an indoor air quality sensor (e.g., a carbon monoxide detector) and determines if the received indoor air quality information is less than a predetermined threshold value. In some embodiments, controller 2000 receives information from any of one or more controller, one or more equipment devices, one or more sensors, a network, etc., and determines an operation of user interface 2032 and/or LEDs 2026 based on the received information. Controller 2000 may receive information through a wired connection at input interface 2024, a wireless connection at input interface 2024, or a combination of both.

In some embodiments, sensor/equipment module 2010 determines an event based on the received information and provides the event to LED module 2008.

For example, in some embodiments, if sensor/equipment module 2010 receives temperature information from sensor/equipment 2036, sensor/equipment module 2010 provides the temperature information to user interface module 2020. In some embodiments, user interface module 2020 is configured to determine control signals for user interface 2032 to display the information received from sensor/equipment module 2010 to a user. In some embodiments, sensor/equipment module 2010 is configured to provide LED module 2008 with at least one of information received through input interface (from at least one of controller 2034 and sensor/equipment 2036) and the determined or received event.

In some embodiments, user interface module 2020 is configured to determine control signals for user interface 2032. In some embodiments, user interface 2032 is user interface 106. In some embodiments, user interface module 2020 is configured to determine control signals for user interface 2032 to display messages, information, graphical representations of information, data, etc. In some embodiments, user interface module 2020 also receives information from user interface 2032 through input interface 2024. In some embodiments, user interface module 2020 receives commands, directives, requests, etc., from user interface 2032 and adjusts an operation (e.g., a displayed message) of user interface 2032 based on the command, request, etc., received from user interface 2032. In some embodiments, user interface module 2020 receives a request from user interface 2032 to display certain data, and user interface module 2020 adjusts an operation of user interface 2032 to display the requested data.

In some embodiments, controller 2000 receives any of information and an event from controller 2034. For example, in some embodiments, controller 2034 is communicably connected with sensor/equipment 2036 and is configured to analyze, process, group, etc., information form sensor/equipment 2036 and determine if an event has occurred. In some embodiments, controller 2034 provides the information and/or event data to at least one of user interface module 2020 and LED module 2008.

Referring still to FIG. 20, memory 2006 is shown to include LED module 2008, according to some embodiments. In some embodiments, LED module 2008 is configured to determine an operation of one or more LEDs (e.g., LEDs 2026, LEDs 1004) based on information received from any of sensor/equipment module 2010, user interface module 2020, user interface 2032, controller 2034, and sensor/equipment 2036. LED module 2008 determines any of a color, a pattern, an intensity, etc., of the one or more LEDs based on the received information and determines signals to adjust an operation of one or more LEDs based on the received information.

LED module 2008 is shown to include an LED database 2012, a color module 2014, a pattern module 2016, and an intensity module 2018. In some embodiments, LED database 2012 stores information regarding a patterned operation of one or more LEDs based on a received event and/or received information. For example, if LED module 2008 receives an event from sensor/equipment module 2010, controller 2034, sensor/equipment 2036, etc., indicating that the indoor air quality has dropped below a predetermined value, LED module 2008 may retrieve a set of instructions from LED database 2012 regarding an operation of LEDs based on the event. In some embodiments, LED database 2012 includes information regarding an operation of LEDs for a variety of events, including but not limited to, an increased temperature event, a decreased temperature event, a low indoor air quality event, an emergency event, a fire detection event, an equipment failure event, a calendar date event, a time of day, etc. In some embodiments, LED database 2012 includes a set of predetermined instructions regarding an operation of LEDs for each of these events.

In some embodiments, LED database 2012 includes a set of predetermined instructions for each of a set of predefined events. In some embodiments, LED database 2012 can be updated and/or customized. For example, in some embodiments, LED database 2012 can receive directives from user interface 2032 to change an operation of one or more of the LEDs (e.g., color, on-off pattern, intensity, timing, etc.) to modify the predetermined instructions for one or more of the predefined events. In some embodiments, additional events can be added to LED database 2012 along with corresponding LED operation instructions for the additional events. In some embodiments, for example, controller 2000 includes a wireless radio (e.g., a Bluetooth wireless radio) configured to interface with a user device (e.g., a smartphone). The LED database 2012 is configured to be updated or modified based on directives received from the user device. For example, if a user wants to be notified/reminded of an event on a certain date at a specific time, the user may add an event to LED database 2012 to adjust an operation of one or more LEDs according to a predetermined pattern, set of rules, etc., on the certain date at the specific time.

In some embodiments, upon receiving an event and/or information, LED database 2012 provides the instructions to color module 2014, pattern module 2016, and intensity module 2018. For example, if LED database 2012 receives a night-time event (e.g., from a clock or from a light detector), LED database 2012 may retrieve a specific set of instructions (e.g., dim all LEDs by 50%, turn off several LEDs, adjust a color of one or more LEDs to blue, etc.) for the LEDs (e.g., LEDs 2026, LEDs 1004, etc.) corresponding to the night-time event.

In some embodiments, LED database 2012 includes instructions for various events to adjust a color of one or more of the LEDs (e.g., red, blue, green, etc.), adjust an intensity of one or more of the LEDs, turn one or more of the LEDs on or off, patterningly adjust a color of one or more of the LEDs, patterningly adjust an intensity of one or more of the LEDs, patterningly turn one or more of the LEDs on or off, etc. In some embodiments, any of the color, intensity, on/off state, etc., of the one or more LEDs is patterned over time (e.g., all LEDs are turned on for 5 seconds, then turned off for 5 seconds, and this is repeated), or patterned based on a predetermined position of the one or more LEDs (e.g., turn a first LED on, then turn a second LED on, then turn a third LED on and turn the first LED off, then turn a fourth LED on and turn the second LED off, then turn a fifth LED on and turn the third LED off, etc.), or patterned based on both time and position of the one or more LEDs.

In some embodiments, one or more of the set of instructions stored in LED database 2012 extend for a time duration, and are repeated. For example, some of the sets of instructions may last for five seconds (e.g., a patterned operation of the LEDs for five seconds) and be repeated a predetermined number of times, while other sets of instruction may last only two seconds (e.g., increase intensity from 0% to 100% for all LEDs over a 1 second time duration, then decrease intensity from 100% to 0% for all LEDs over a 1 second time duration), and repeated.

In some embodiments, sets of instructions are combined. For example, in some embodiments, all events which indicate an increase in temperature include a same patterned intensity operation of LEDs (e.g., linearly increase intensity of all LEDs from 0% to 100% over a five second time window). However, within the set of all events which indicate an increase in temperature, other operations of the LEDs (e.g., color) may vary based on other factors (e.g., which temperature from a set of temperatures is increasing, how fast the temperature increases, etc.).

Any of the color, pattern, intensity, etc., of the one or more LEDs may be adjusted over a time window linearly (e.g., increase intensity from 0% to 100% linearly over a 5 second time window) or may be adjusted over a time window non-linearly (e.g., increase intensity from 0% to 100% according to an exponential function, a polynomial, etc.).

In some embodiments, the instructions stored in LED database 2012 depend on the particular types of LEDs used. For example, some LEDs may not be multi-color LEDs and may only actuate between an on state and an off state, according to some embodiments. In some embodiments, LED database 2012 stores a map of positions of the LEDs and abilities of each of the LEDs (e.g., dimming abilities, maximum light intensity, etc.).

In some embodiments, controller 2000 does not include LED database 2012, and receives instructions from any of controller 2034 and/or a network to adjust an operation of any of a color, a pattern, an intensity (e.g., dimming), etc., of any of the LEDs.

Referring still to FIG. 20, LED module 2008 is shown including color module 2014, pattern module 2016 and intensity module 2018. In some embodiments, color module 2014, pattern module 2016, and intensity module 2018 are configured to determine any of voltage, current, digital signals, analog signals, etc., to adjust an operation of one or more LEDs according to the determined operation received from any of LED database 2012, controller 2034, etc. LED module 2008 may include any predefined script objects, functions, or electrical components (e.g., resistors, capacitors, inductors, transformers, etc.) necessary to determine voltage, current, etc., required to operate the LEDs to produce the desired operation. In some embodiments, LED module 2008 uses Pulse Width Modulation and adjusts a duty cycle to change a brightness of one or more of the LEDs.

In some embodiments, LED module 2008 is connected to one or more LEDs (e.g., LEDs 2026, LEDs 1004, etc.). In some embodiments, LED module 2008 adjusts an operation of the one or more LEDs to produce the desired effect (e.g., dimming, changing color, patterned dimming, patterned change in color, etc.). In some embodiments, the one or more LEDs each correspond to one or more wave guide 1504 to any of diffuse, direct, scatter, focus, etc., light emitted by the one or more LEDs along sides 108 of display device 100.

Additional Examples

Referring now to FIGS. 21-22, display device 100 is shown, according to some embodiments. In some embodiments, display device 100 is configured to display a multicolored status bar 2202. In some embodiments, multicolored status bar 2202 is at a center of a display screen of display device 100. In some embodiments, multicolor status bar 2202 varies in color along its length from red to yellow to green and then back to yellow to red. In some embodiments, an indicator 2204 (shown as a white tick mark) shows a current real-time pressure on multicolored status bar 2202. In some embodiments, the current real-time pressure represents a current alarm status. In some embodiments, as the pressure reading ventures outside of the normal operating range (indicated by the green section of multicolor status bar 2202), the indicator 2204 (e.g., a real-time indicator) moves towards the yellow section of the multicolor status bar 2202 indicating a warning condition. In some embodiments, if the pressure continues away from the normal operating range beyond limits of a warning range, and enters an alarm range, the indicator 2204 moves into a red section of the multicolor status bar 2202 indicating an alarm condition. In some embodiments, display device 100 displays text 2206 representing the differential pressure (e.g., in “wc) which tracks the gradient color of the multicolor status bar 2202. In some embodiments, a color of light emitted through halo 112 tracks the gradient color of the multicolor status bar 2202. In some embodiments, this provides an overall consistent display device 100 rather than just displaying red, yellow, or green for alarm, warning, or normal, respectively. In some embodiments, halo 112 tracking the gradient color of the multicolor status bar 2202 (or a corresponding color of multicolor status bar 2202 at indicator 2204) provides consistency with the rest of display device 100.
